Answer:
D. p>-3
Step-by-step explanation:
step1
move 12 to the other side
p>9-12
when you move it changes it's sign from positive to negative
p>-3
Answer and Step-by-step explanation:
The data represent sample of five men and five women conducted a randomization test to compare the sexes on the variable pulse.
The samples revealed that in 120 out of 252 possible outcomes under randomization have large difference. From this information it cannot be concluded that the sexes differ with regard to pulse.
The hypothesis test should be conducted between treatment and response for valid conclusion. The student can consider the biological content of men and women or verbal statements. The answer varies from person to person according to their respective data set. Therefore, it cannot be concluded that the sexes differ with regard to pulse.
This data is discrete because it does not form a straight line when plotting the information on a data graph.

Answer:
x = 10
y = 6
Step-by-step explanation:
<u>Vertical Angle Theorem</u>: When two straight lines intersect, the opposite vertical angles are always equal to each other.
⇒ m∠1 = m∠3 and m∠2 = m∠4
⇒ m∠1 = m∠3
⇒ 10x = 100
⇒ x = 10
<u>Linear pair:</u> Two adjacent angles which sum to 180°.
⇒ m∠1 + m∠2 = 180°
⇒ m∠3 + m∠4 = 180°
⇒ 100 + 10y + 20 = 180
⇒ 120 + 10y = 180
⇒ 10y = 60
⇒ y = 6
